Liverpool winless run continued as rivals Everton earned a rare Merseyside derby victory with a 2-0 result at Anfield on Saturday.
Goals from Richarlison and Gylfi Sigurdsson in each half were enough for Everton to secure their first derby victory at Anfield since 1999.
The result means that Liverpool suffered their fourth consecutive defeat in the league and fourth in a row at home.
Jordan Pickford then made a number of important saves to deny Jordan Henderson, Sadio Mane and Mohamed Salah as the hosts tried desperately to get back level.
However, Dominic Calvert-Lewin was brought down inside the box late on and Sigurdsson confidently scored from the spot as Everton secured a famous win that moves them level on 40 points with the Reds.
Liverpool, with several players unavailable, also suffered a further injury setback as Henderson limped off in the first half.
Defeat for Liverpool continued the defending champions' poor form in the Premier League as they have now lost their past four fixtures and are three points behind fourth-place Chelsea.
Meanwhile West Brom boss Sam Allardyce says his side produced one of the best performance by 10 men he has seen as they were held to a goalless draw by Burnley.
The Baggies secured their first clean sheet since 28 November despite the first-half dismissal of Semi Ajayi.
And although the point did little to boost their hopes of avoiding relegation - they are 11 points adrift of safety - Allardyce was pleased with what he saw.
